Tajchs Large and Small Vodárenská together with Červená Studňa, they are located directly above the medieval heart of the town in the valley above Holy Trinity Square. According to written records they are the eldest reservoirs in the Štiavnica Mountains, their origin reaching back to 1500. Although the name (Vodárenská – related to water station) might suggest they used to be the sources of drinking water, they were also used for driving water pumps and stamp mills in their early years. The Large Vodárenská Tajch is the only reservoir whose dam broke – in the early morning of 22nd January 1633. The water rushed down to the town underneath, resulting into collapse of three houses, destruction of many more buildings and deaths of five people.
